E! is reporting that there’s some trouble on the set of the ABC drama Brothers and Sisters as a result of everyone’s favorite vandalized slut (see below), Sienna Miller. Co-stars Balthazar Getty and Matthew Rhys are reportedly family feuding because Getty is currently dating Miller, who happens to be Rhys’ ex. Seems Getty placed his ho before his bro when he started his relationship with Miller, failing to tell Rhys anything about the relationship.

Of course in the early days of the relationship, Getty was still married to wife Rosetta (they’re currently separated and filing for divorce), so it’s safe to assume he wasn’t telling many people about the affair. It was only after the topless pics of Miller, vacationing with Getty in July, were released that things got awkward.

Now that the show has resumed filming though and Rhys and Getty have to see each other every day, someone should get Sienna a bra — things are a little chilly around here. [Top photo: Getty Images; Below: Splash News Online]
